For Basic Operation
5.4 For Stable Measurement in Semi-micro Range
(AUW-D series only)
The small range (semi-micro range, minimum display 0.01mg) of AUW-D series dual range balances
produces excellent response and stability. However, weighing in the 0.01mg range is generally more
subject to the environment and how measurements are performed compared to the 0.1mg range.
When using the small range of AUW-D series, observe the following instructions in order to obtain the
best result.
Avoid air current from the air conditioner. When the air conditioner is in operation, the temperature of
the air current from it has a large difference from the room temperature. Air current and presence of dif-
ferent temperatures both make the measurement unstable.
The temperature of the balance does not change as fast as the room temperature. Changing room
temperature prior to measurement causes temperature difference remaining for a long period. Even
without direct blow of air current, contact of air of different temperatures generate air convection in the
weighing chamber and result in unstable display.
• Leave the glass doors open while not in use. This prevents temperature gap between weighing
chamber and ambience.
